SAA-C03 Q352 · Storage

Question

A company is developing a content sharing platform that currently handles 500 GB of usergenerated media files. The company expects the amount of content to grow significantly in the future. The company needs a storage solution that can automatically scale, provide high durability, and allow direct user uploads from web browsers. Which solution will meet these requirements?

Accepted Answer

Amazon S3 Standard satisfies every requirement:

1. **Automatic Scaling**: S3 is an object storage service with virtually unlimited capacity. There is no provisioning needed — you simply upload objects and S3 scales automatically from 500 GB to petabytes and beyond.

2. **High Durability**: S3 Standard provides 99.999999999% (11 nines) durability by automatically replicating data across a minimum of 3 Availability Zones within a region. This is the highest durability of any AWS storage option.

3. **Direct User Uploads from Web Browsers**: S3 supports **presigned URLs** and **presigned POST** policies, which allow your application to generate a temporary, secure URL that end users can use to upload files directly from their browsers to S3 — bypassing your application servers entirely.
